Question 15

voltage of a cell

Answer 15

what helps to push charges around a circuit

Question 16

electromagnet

Answer 16

a magnet you can turn on and off

Question 17

motor effect

Answer 17

a wire carrying a current creates a magnetic field, the motor effect is when the magnetic field created interacts with another magnetic field
